no projector. i know i really should have projectors with HID, but i am asking bc i know many on here have them installed w/ out projectors and so thats why im wondering.
HIDs...daaang they're bright.
i know many of you on here have installed HID kits to your fortes..
1) how often do you get high-beams flashed at you (or just put on and they leave them on as they are driving towards you) since you have put your HIDs in? i've seen it talked about briefly during posts of people's hid threads, but i jus want to hear from yall here..
i've had mine in since saturday, and tuesday night i was coming home with almost every other car flashing high beams at me... :/
i adjusted the lights when i got home, but now they seem too low...i dont feel like i am getting the distance of light as i should. i tried setting them, and walking out from my car and walking towards it (100ft+ then back) and daang they are bright lights shining at you.
(i also have 6000K fogs in) and for those of you who have HID fogs,
2) do you run your fogs all the time? im used to the extra light from the fogs running, and i hate not running them (for my own sake..hah)
3) anyone been pulled over for having lights so bright the police think you're running your highs all the time?
4) so what do yall do to keep from high beams always being shined back at you? or police pulling you over?

Projector (polyellipsoidal) lamps
Projector optics, side view
Projector headlamps on an Acura RL
In this system a filament is located at one focus of an ellipsoidal reflector and has a condenser lens at the front of the lamp. A shade is located at the image plane, between the reflector and lens, and the projection of the top edge of this shade provides the low-beam cutoff. The shape of the shade edge, and its exact position in the optical system, determines the shape and sharpness of the cutoff.[14] The shade may have a solenoid actuated pivot to provide both low and high beam – the shade is removed from the light path to create high beam, and placed in the light path to create low beam, and such optics are known as BiXenon or BiHalogen projectors, depending on the light source used. If there is no such arrangement, the cutoff shade is fixed in the light path, in which case separate high-beam lamps are required. The condenser lens may have slight fresnel rings or other surface treatments to reduce cutoff sharpness. Recent condenser lenses incorporate optical features specifically designed to direct some light upward towards the locations of retroreflective overhead road signs.
Hella introduced ellipsoidal optics for acetylene headlamps in 1911, but following the electrification of vehicle lighting, this optical technique wasn't used for many decades. The first modern polyellipsoidal (projector) automotive lamp was the Super-Lite, an auxiliary headlamp produced in a joint venture between Chrysler Corporation and Sylvania and optionally installed in 1969 and 1970 full-size Dodge automobiles. It used an 85 watt transverse-filament tungsten-halogen bulb and was intended as a mid-beam, to extend the reach of the low beams during turnpike travel when low beams alone were inadequate but high beams would produce excessive glare.[21]
Projector main headlamps first appeared in 1981 on the Audi Quartz, the Quattro-based concept car designed by Pininfarina for Geneva Auto Salon.[citation needed] Developed more or less simultaneously in Germany by Hella and Bosch and in France by Cibié, the projector low beam permitted accurate beam focus and a much smaller-diameter optical package, though a much deeper one, for any given beam output. The version of the 1986 BMW 7 Series sold outside North America was the first volume-production auto to use polyellipsoidal low beam headlamps.

Glare
Vehicles equipped with HID headlamps are required by ECE regulation 48 also to be equipped with headlamp lens cleaning systems and automatic beam levelling control. Both of these measures are intended to reduce the tendency for high-output headlamps to cause high levels of glare to other road users. In North America, ECE R48 does not apply and while lens cleaners and beam levellers are permitted, they are not required;[33] HID headlamps are markedly less prevalent in the US, where they have produced significant glare complaints.[34] Scientific study of headlamp glare has shown that for any given intensity level, the light from HID headlamps is 40% more glaring than the light from tungsten-halogen headlamps.[35]
